Hi @christophstrobl. I am new to contributing to spring-data-mongodb. Can I handle this issue?

[christophstrobl]

Hi @mihailcornescu! That would be very kind. Please make sure to follow our contribution guidelines. Thank you.

Thank you @christophstrobl. I have checked them already. Can you tell me for which milestone should I include the changes? In other words or from which branch should I create my feature branch.

[christophstrobl]

Please use main. We'll take care of porting the changes.

@christophstrobl I have raised PR #3950. Can you have a look on it?
